Simulation Analysis Of Multi-runway Configuration Traffic Flow Operation

With the further development of reform and opening,the contradiction between the surge in the total volume of civil aviation transportation and the limited operating capacity of airports has become increasingly prominent.Since a considerable number of airport planning and design units usually use the data from the relevant US airport design manual to determine the airport capacity,and the domestic operating environment has many inconsistencies with the manual,it often leads to saturation operation earlier than expected after the airport is completed.In recent years,the number and scale of multi-runway airports in China have been continuously expanded.In order to reduce investment risks,it is necessary to accurately determine the planned runway configuration capacity during the planning stage.From the perspective of operational planning,this paper analyzes the relationship between operation mode and traffic flow in multi-runway configuration airport by computer simulation.Firstly,the aircraft take-off and landing process is modeled.The take-off process adopts the model based on aircraft performance,and the landing process adopts the kinematics model based on QAR data correction.Secondly,based on the take-off and landing model,a single-runway airport traffic flow operation model is established.The model uses the discrete event simulation principle,and generates the approach and departure traffic flow by Monte Carlo method,the stimulus-response model in the following principle is used to adjust interval and speed between the aircrafts;Thirdly,based on the single-runway traffic flow operation model,the multirunway configuration traffic flow operation model is established,and the complex runway configuration is decomposed into the basic runway configuration block.The operation mode of the runway is selected by the model according to the configuration information and the characteristics of the traffic flow;Finally,use the multi-runway traffic flow operation model to simulate the Baiyun Airport expansion plan and the Daxing Airport operation plan,to explore the relationship between the runway operation mode,traffic flow and runway capacity.The simulation results prove the advantages of Baiyun Airport's new planning scheme and gives reasonable suggestions for the runway operation of Daxing Airport.In this paper,the computer simulation method is used to study the traffic flow problem under multi-runway configuration conditions,and the related factors affecting the operation of the airport are analyzed,which can provide some reference for the future planning and operation of the airport.
